Simple issue the items on the catalog with the sale banner have a z-index issue which makes the banner appear behind the item photo.
exs:
This happened with another gear recently, though I don’t remember which one specifically. It came out in the same wave as the Colassal Flames Golem.
It’s possible this could be intentional. It really makes the item image pop out.
And it’s not just the sale banner, it’s also the limited banner.
It also happens in 3D view.
